45 Claims. (Cl. 197133) This invention relates to devices for controlling the record supplies of billing machines, typewriting machines, and the like, and, with respect to its more specific features, to devices of the 5 character referred ,to for effecting registration, with each other, of superposed printed forms printed on a large number of long paper record strips. I

One of the main objects of the invention is the provision of a practical device of the character referred to wherewith successive accurate registration of superposed printed forms may be effected safely, positively and quickly, especially when a large number of relatively superposed record strips are utilized.

Another object "of the invention is the provision of. an efiicient and simple device of the character referred to by which accurate registration of a large number of superposed printed forms may be effected and displacement of the strips from registration relative to each other positively corrected.

Other objects of the invention will in part be' obvious and will in part appear hereinafter.

2 g The invention accordingly comprises the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying. drawings, in

'55 Referring now more specifically tothe drawings, the numerals 1 indicate paper record strips suitable for manifolding use. These strips may be supplied from a packet 2 composed of a plurality of strips 1 folded zigzag along weakened lines 3 in each strip. Each strip 115 provided 5 with a longitudinal series of printed forms 4. To bring the strips in position for inscription the foremost printed forms on superposed strips are registered with each other in superposed relation, with the interposition of transfer material, such as separate carbon sheets, between superposed strips, 'so that an inscription made on the topmost printed form will be duplicated in the same relative position on the underlying forms regis -tering therewith. For each printed form two pairs of transversely alignedcircular form-registering apertures 5 are provided in each strip, the apertures and forms being in such relation to each other in each of the strips that, when the pairs of apertures of the strips are in superposed registry, the adjacent superposed forms are also in registry.

The numerals 6 indicate two front strip-aligning pins or hooks, providing a strip aligning device mounted on the frame of the billing maso chine adjacent the front end of the platen. These pins are preferably oval in cross section and smaller in cross section than the apertures 5 inthe strips 1. The numeral '7 indicates a suitably apertured clamping jaw, or plate, movable into or out of position to clamp strips 1,

which have their apertures 5 in engagement with th pins 6. Movement of theplate 7 to and from gripping position may be effected as hereinafter described. The upper side frames of the billing machine are indicated at 8, and the platen 9 may be supported thereby. It will be understood that the advance ends of superposed record strips 1 are'gripped together by the operator and lifted from the pins 6 after the plate '1 has been raised, the strips then being simultaneously advanced, fed, or pulled by the operator until the next set of superposed apertures 5 is placed in engagement with the pins 6, whereupon the plate 7 may be restored to clamping position to hold 10 the strips adjacent the pins 6. Over the platen 9 may travel a typewriting machine for making the direct inscription on the topmost record strip, as well understood.

Detachably mounted between the two side frame members 8 forming supports or supporting arms extending rearwardly of the platen 9, is Y a rigidmetal carriage support or auxiliary supporting frame which may be composed of the two oppositely disposed side members 10 and 11,

held, together by the cross pieces 12 and 13, in turn longitudinally braced by the plates 14 and 15 joining the frame members 12 and 13. The carriage support may be securely stationarily held on the frame by the four clamp jaws 16 and thumb screws 17, the latter of which may pass through openings in the frame members 10 and 11. The carriage or auxiliary supporting frame is thus demountably held in place, and it may be readily lowered into position or raised therefrom.

Mounted for longitudinal reciprocal movement on the carriage support is a strip drawing frame or carriage providing a longitudinally oscillatable supporting slide composed of the two side plates 18 and 19, between which extend a number of parallel strip guide bars 20, each of which bars is rotatively mounted in the side plates 18 and 19. As will be perceived hereinafter, the bars 20 are adapted to act as gripper jaws. The numerals 21 indicate gripper fingers carried by respective bars 20. In the embodiment illustrated three gripper fingers are carried by each jaw, each gripper finger being a thin metal blade or plate fixed to the intermediate fiat under surface 22 of the bar 20, and projecting from one bar 20 into lapping relation with the next adjacent bar. The plates 21 together with the bars 20 and associated parts thus constitute a friction plate device for alignment and control of the record strips, embodying a pile or assembly of friction plates for individual cooperation with the record strips r as later more fully described. On each of the gripper carrying bars 20 is a radially extending ,bar rotating pin 23, these pins being disposed at opposite ends of alternate bars 20.

Carried by each of the side plates 10 and 11 are the transversely projecting trips, or trip pins, 24, against which the bar rotating pins 23 are adapted to contact as the carriage is reciprocated, the trip pins being disposed in the path of the bar rotating pins 23 and being spaced from each other along the line of reciprocation of the carriage. For rotating each of the bars 20 in one direction, springs are provided, these springs being indicated by the numeral 25, one end of each spring being anchored to holding pins 26 projecting from the plates 18 and 19, respectively, the opposite end of each spring having an eye engaging the base of the bar rotating pin 23, each spring partially encircling its bar 20, and the stress of the springs being adapted tocause the fingers 21 to exert a gripping elfect in cooperation with an adjacent bar 20. For supporting the drawing frame or slide for reciprocal movement, upper and lower sets of rollers 27, carried by the frame members 10 and 11, may be utilized. In

' this wise easy movement of the drawing frame is made possible. Each plate 18 and 19 thus forms a slide or slide member. The strip guide bars 20 are journaled in these slide members.

For reciprocating the drawing frame or carriage a pedal 28 fulcrumed at 29, and having an adjustable connecting rod 30 may be employed. The upper end of the connecting rod 30 is pivoted to an arm 31 of a rock shaft 32, said shaft being journalled in the supporting frame members 10 and 11 beneath the drawing frame, and having at its opposite'ends cranks 33, the outer ends of which have slots 34 (see Fig. 5) engaging the foremost of the bars 20. .In one of the side frames 10 or 11 of the carriage support is an aperture through which may project an upholding pin 35 outwardly pressed by a leaf-spring 36. The carriage support, including the side frames 10 and 11, may be pivotally mounted on the frame members 8 near its front end. This pivotal mounting may be effected by having the front screws 17 serve as pivots, and by providing a slot 37 in each of the carriage support members 10 and 11, so that the carriage support may be upwardly rotated on the forward screws 17, whereupon the pin 35 will be projected by its spring into position to engage the upper surface of a side frame 8, and thus uphold the carriage frame in convenient position for threading the record strips in relation to the several grippers of the drawing frame.

For actuating the clamping jaw 7, it is operatively connected to a lever 39 consisting of a yoke fulcrumed on an axis 40, in a system of levers, the two arms of the yoke being operatively connected to the jaw 7, through the system of levers, to raise and lower said jaw. To the cross piece 41 of the yoke is connected a depending link 42, the lower end of which is pivoted to the treadle 28 at 43, said treadle being fulcrumed at 29 on a depending stationary bracket 44. The axis is a shaft having its opposite ends in a pivotal connection with the levers 45, which are fulcrumed on the side frames 8 at 46. To the ends of levers 45 are pivoted the levers 47, fulcrumed on a cross rod 48 supported by the side frames 8, the ends of levers 47 being bent upwardly and having the clamping jaw 7 fixed thereto. On lever 47 is an arm 49, to which is connected one end of a strong spring 50, the other end of spring 50 being fixed, as to the fulcrum 46. The spring 50 causes clamping jaw 7 to descend and clamp the record strips adjacent the aligning pins 6,'and it acts in opposition to depression of the treadle, or foot pedal, 28. It will also be noted that said spring 50 acts as an operating member and, through the link 42, pedal 28, connecting rod 30, rock shaft 32, and rock arms 33, not only lifts the pedal 28, but participates in effecting strip drawing movement of the gripper carriage, and thereby effects simultaneous drawing movement of all the grippers with substantially equal force. The spring, or resilient device 50 also moves the carriage or slide rearwardly to separate the finger actuating members 23 from the trips 24 so as to permitthe individual springs 25 to effect closing of the several grippers, and also yieldingly holds the slide in retracted position.

In operation the several record strips coming from the zigzag folded supply 2 (see Fig. 4) are threaded between the respective gripper fingers 21 and the next adjacent forward bar 20, this preferably being effected most conveniently when the carriage supporting frame is held in an elevated position by the pin 35. When the carriage support is swung upwardly about its pivot 17, it will be observed that the link 30 becomes operative to move the carriage forwardly, thus separating aligning pins 6. If now it.be assumed that the next succeeding set of superposed printed forms is to be advanced to position over the platen, the

foot pedal 28 is depressed. This results in simultaneous advance movement of the plurality -of pair's of strip grippers, each pair being composed of a se t of the blades 21 and the next adjacent bar 20. T his approaching movement between the drawin \g grippers and the aligning pins 6 will evenrtu: ally bring the bar rotating pins 23, practicallyr simultaneously, into contact with the trip pins 24, with the result that simultaneous opening moveeme mt of the grippers will occur, and the several strips thus he. released from substantial drawing engagement. of the grippers with the strips. The gripping: effect on the strips having been reliieved, the. superposed strips may readily beadvanced by hand. simultaneously, free of substantiial gripping eifect,.and the next succeeding set of apertures engaged with the pins 6. Therleupon, on release of the foot pedal 28, the spring 50, through its connections hlereinbefore referred to, will cause rearward movement of the gripper carriage, and the grippers being in yielding frictional engagement with the respective strips will draw each ofthe strips; into aligning position, with. the forward edges of the apertures 5 in engagement with the front faces of the stripaligning pins 6. When the gripper carriage thus moves rearwardly the operating pins 23 will disengage the respective trip lugs 24 whereupon the movable gripper fingers or blades 21 will be moved into yielding engagement with the respective companion gripping members or bars 20 by operation of the tensioned springs 25.. The several strip grippers thus move. together as a unit or group in strip aligning direction, the grippers individually engaging with the. several strips so as to effect independent. or individual alignment thereof. It will be noted that, although the drawing movements: of the grippers are simultaneous. the strips are separately, yieldingly or frictionally engaged by the plates 21 so that, should the aperture edges of one strip reach the front face of pin 6 before the aperture-edges of other strips, these latter WllLllBVGI'tITiBlBSS; be drawn into aligning position against said pins, the grip engagement on the already aligned strips yielding to permit the others to be drawn into alignment. In this wise strips drawn to aligned position against the pins 6 may stop, while other strips may subsequently be moved to aligning position. Thus means are provided for positively drawing each strip into aligning; position in respect to the pins 6 and without danger of tearing the strips or the edges of the aligning apertures therein; Inasmuch as the strips are separately gripped, they will be individually aligned by the action described, and it will beobvious that this aligning action of the strips takes place while the apertures thereof are engaged by the pins 6, but while the bar 7 is slightly raised in released position so as to permit free aligning action of the stripsupon the pins after which aligning action the bar 7 may descend into contact with the strips. It will accordingly be seen that the device provides a very simple means for-aligning and registering printed superposed forms on a grea-t number of strips. No difficulty is encountered in aligning and'registering as many as twelve relatively superposed contiguous strips, and more or less may be employed if desired.

In the embodiment illustrated in Figs. 6 to 9, inclusive, a somewhat modified construction is shown. In this modified construction the outer side pieces 10 and 11 have flanges and 61, providing stationary frame members which are slotted at intervals, as illustrated at 62. The slots 62 may be formed by slitting the flange and striking down the slitted part so as to form a projecconstruction and different embodiments of the tion, or trip 63, the material of the flange at the opposite side of the slot forming a second-trip 64, the under face 6.5 of the flange providing a keeper track, said track and the trips being thus integralparts of the respective frame members 60 and 61. Also, in this modified form, the gripper fingers, corresponding to thefingers 21 of the previously described form, each has a facing cushion 66 of soft material, such as a felt pad. As illustrated in Fig. 9, the pad 66 may be held on the bar 20 by a metal backing 6'7, which backing may be spot-welded to the bar 20, the backing 67 having struck-up, bendable clips 68 adapted to penetrate the cushion 66 and retain the cushion on the back 67. The cushions 66 are preferably relatively thick and have some individual resiliency, although they are soft. The bar-rotating pins are indicated at 69, and in this modified form have beveled endsas shown. In Fig. '7 the carriage is illustrated in its rearward position. When the treadle 28 is depressed, the bar-rotating fingers 69 are moved to the left, and their beveled ends or cam surfaces come into contact with the corresponding cam surfaces of the trips 63, whereupon continued leftward movement of the carriage causes the ends of the fingers .69 to enter between the sets of trips 63 and 64, thus effecting rotation of the bars 20 and causing the gripper fingers to release, or relieve, their grip on the strips, the last position of the fingers being illustrated in Fig. 8. Upon releasing the treadle 28, the carriage will be moved to the right from the position illustrated in Fig. 8. At the beginning of the movement to the right the trips 64 at the ends of the tracks will cause fingers 69 to rotate anti-clockwise, and thereby cause the gripper fingers to move to position to grip the record strips. Continued movement of the carriage. to the right will draw the fingers 69 beneath the keeper tracks 65, which tracks will thereafter limit clockwise movement of the gripper fingers. A yielding and a somewhat resilient grip on the strips will nevertheless be maintained. on account of the cushions 66 which are somewhat compressible. Thus in this modified construction, the movements of the gripper fingers. are effected. practically in a positive manner with the use of fewer and stronger separate parts than in the form previously described.

Thus by the above described construction are accomplished, among others, the objects herein before referred to.
